Abstract


The Calcium Silicate Hydrate (CSH) family mineral such as Xonotlite (X), Tobermorite (T) was synthesized by hydrothermal method using rice hush and CaO as the Si and Ca supplier. The rice hush (RH) was burnt inside the furnace at 500oC for 2hrs to obtain the rice hush ash (RHA), then mixing with CaO with the Ca/Si 1.0, and hydrothermal treatment at 110oC for 24h to obtain Xonotlite and Tobermorite mineral with micropore structure (coded as CSH-110/24). The CSH 110/24 samples were used to remove Chrome (III) in 2,4 and 6 hours, with fast removal phenomena. This research can be applied in metallurgy industry such as removal Chrome (III) during the Chrome-coating process.
